Question

Please make additional adjustments to the C++ code. There is only one infrared LED. If a non-moving train is detected (and stops for a few seconds), the LED should be turned on. The LED should always stay turned off if:

  • There is no train detected
  • At least one train bypasses without stopping
Expert Solution
Step 1: Introduction

The subject matter under discussion concerns the regulation of an infrared LED by its detection of a stationary train. In this case, our goal is to write a C++ application that uses a fictitious detection method to keep track of the existence of a train. We specifically aim to accomplish the following behavior:

  •     An infrared LED need to be activated if a train is detected as stationary and stays motionless for a brief period of time.
  •     If the LED is not spotted by a train, it should always stay off. One train, at least, goes by without stopping.

The train's location and whether it has been stationary for the predetermined amount of time are tracked by the implementation using a continuous loop. The program turns on the LED when these requirements are satisfied.

In the actual world, this situation might be used at train stations or crossings when it's necessary to signal the presence of a stationary train for operational or safety reasons. In real implementations, more intricate train detection and LED control techniques would be used; the code that is provided is merely an example.
